Abstract

An improved sol-gel process is disclosed for fabri-cating large monoliths of silica or ceramic material, which are substantially free of cracks. Following forma-tion of the gel, but before the gel is dried, the gel is sub-jected to a hydrothermal aging treatment (50), in which it is heated in an autoclave to a temperature of between 100 and 300 °C, for a time duration of a at least about one hour. This hydrothermal aging treatment causes sili-ca (or ceramic) particles to migrate and fill small pores in the porous gel matrix, such that the average pore size increases and capillary forces encountered in the subse-quent drying step (70) are reduced to a point where cracking of the gel is substantially eliminated.
